Check for the magic file "/.rockbox/skin_buffer_size.txt" on bootup which can have a number which is the amount of kilobytes to allocate for the skin buffer. This is only checked on boot so if you need to change it you must reboot to enable.

Currently the default size is 80KB on colour targets which can be way too much or not enough for users.
The format of the /.rockbox/skin_buffer_size.txt file is simply a number (so 120 if you want 120 kilobytes), NO trainling spaces or text of any kind
